One of the most popular ReFabs on this blog is an amazing lamp makeover using duct tape and 2L soda bottles. Classy upcycling of plastic bottles never gets old for me.
This lovely tutorial (care of Instructables) is my new favorite. Because it's thrifty and simple. And the instructions are great. They're calling it a Designer Paper Lamp. I think the more important thing to call out is that it's upcycled soda bottle lighting!
